Step 4 is including the leading double quote.

BTW, at step 5 it shows "1 matches" but after step 6 it shows "replaced 0 matches".

Thanks for the report. I pushed a fix, please let me know if it works.

Out of curiosity: how did you come up with the trailing empty group? I can't think of a practical use. Without it, the error did not occur.

It does, thanks!

I reduced the regular expression from a more complex one: "\(if \(.*\)?, \)?\(.*?\). I've confirmed that the fix works with the longer expression as well.
